Kiloh Nevin Syndrome

As anterior interosseous syndrome is defined as the symptoms at a lesion of the nerve anterior interosseous. The name is derived from the two British neurologists Leslie Gordon Kiloh and Samuel Nevin, who described the syndrome in 1952.

This nerve is a purely motor branch of the median nerve , which innervates the flexors of the end links of the thumb, index and middle finger and the pronator quadratus muscle . As a result, the affected person can no longer form a circle with his thumb and forefinger, among other things. An internal rotation weakness of the forearm ( pronation weakness ) is usually not noticeable, as the pronator teres muscle is mainly responsible for this function . Although this muscle is also innervated by the median nerve, it is not affected in Kiloh-Nevin syndrome, as its motor branch branches off further proximally from the main motor trunk of the median nerve.

In addition to the characteristic clinical findings (nonetheless frequent misdiagnosis: tendon rupture), the diagnosis can be made by an electromyographic examination . The pronator quadratus muscle shows signs of neurogenic damage, while the abductor pollicis brevis muscle (the ball of the thumb innervated by the median nerve) and the pronator teres muscle show no signs of damage. The cause of Kiloh-Nevin syndrome can be a traumatic lesion, but also inflammatory damage, e.g. B. in the context of an arm plexus neuritis. The spontaneous prognosis is usually good, but surgical treatment may also be necessary.
